To all whom it obnoem:

Be it known that I, HOWARD H. TALBOT, a citizen of the United States,residing at Wooster, in the county of Wayne and State of Ohio, haveinvented certain new and use ful Improvements in Coiling Machines, ofwhich the following a. specification.

My-invention relates to the art of reeling or. coiling metal strips, andconsists of a machiiie adaptedrto coil strip steel as it isdelivered'fromthe mill. It has in view to provide' a machine of thistype capable of wind ing the strip around a gripping core, upon an edgesupporting table, capable of lowering adjustment and separation of thecore by the operator on completion of the operation, for removal of thecoil, with various other features of construction and operation, ashereinafter more fully described. Referring to the drawings showing onepreferred embodiment of the invention:

Fig. 1 is a plan view showing the apparatus installed in connection witha mill and delivery table Fig. 2 isv an enlarged plan view of thecoiling machine, partly in section;

Fig. 3 is a side elevation, partly in section; I

Fig.v 4 is a transverse section on the line IVIV of Fig. 3; I

Fig; 5 is a similar partial section showing thelcore fingers lowered forremoval of the 001 v;

V Fig. 6 is a sectionalv detail view showing themountingof one of thecore fingers.

Referring to. Fig. 1, A represents the circular rotatable table of thecoiling machine, two of which are shown in connection with a surroundingplatform flush with the table top, over which the coils may be deliveredto a skid or other receiving device, 1

The. coiling machine. or machines are installed beyond. the delivery endof a slat conveyor B adapted ,to, receive the rolled strip through asuitable guide from the final pass of rolls C, In the event of,additional reduction-before reeling, the table Bis arranged for lateraladjustment, as indicated in dotted lines to bring its receiving end inline supplemental stand. of rolls as will be readily understood. Thestrip a, as

delivered uponthe conveyor from the mill, is not limited as to its speedof travel and may accumulate more or less, as indicated, being deliverededgewise through a pair of vertical guiding rollers. 6 onto the conveyorwhere it may accumulate in looped forma tion, as shown, ready for, beingdrawn therefrom; by the coiling machine;

. Immediately in advance of the coiling machine area series of pivotedrollers 01 around which the strip is laced prior to being led onto thecoiler, for exerting the necessary tension. The active elements of themachine area series of annularlyarranged fingers 2 which extendvertically through the central opening of rotatable table A betweenguidmg lugs 2' thereof, preferablyextending below its upper surface,which is smooth and unobstructed, when the fingers are lowered, as inFig. 5.

Thefingers 2 are of any suitablenumber. as five, and are spaced apart"by the inte vening guides, betweenwhich they are freely movable, leavingample space between any two of the fingers for the insertion edgewise ofthe end of the strip 0. Each finger extends by a projection 3 inwardlybetween upper and lower disks 4:, 5, of an adjusting stem 6 by whichtheentire series are raised and lowered through operating mechanismhereinafter described.

Fingers 2 are each connected with the table by a pair of links7, 7,pivoted at 8 within sockets in their outer lower portion and at 9 towings 10 of an annular hollow post 11 supporting the table by hub 12 onthe upper end of main spindle 13. Hub 12 is keyed to the upper end ofthe spindle and further, secured by a terminal nut 14. and bears bywashers15 upon the. upper end of the central standard frame 16 havingsuitable bushings at each end and an annular oil cup 17. A

Stein 6 extendsdownwardly through the center of spindle 13 and isconnected with a crosshead 26 which is pivotally connected at 27 betweentne bifurcated terminals of a lever 28 of rock shaft 29. A counterweight30 is mounted on an arm 31 also keyed on shaft 29, as a counter-balance,and a lever 32 oi the rock shaft is connected by rod 33 with theoperating lever 34. Said lever is secured to a rock shaft 36 mounted inbrackets depending below the operators platform which is preferably at aslightly higher level than that of table A, and the rock shaft has anoperating handle lever 37 extending upwardly therefrom.

In operation, the end of strip 0 is inserted between two of fingers 2and bent around in hook form, the fingers being elevated. The fingerstogether constitute a skeleton core of annular shape around which thestrip will be wound upon rotation of the table, gradually increasing indiameter until the entire rolled length has been coiled. Suitable outerguards 38'may be utilized, if desired, preterably removable, to retainthe outer free end of the coil, which may be tied around or otherwisesecured, if desired, before removal. After being coiled and the machinebeing stopped, the fingers 2 are lowered to or below the level of thetable A, as in Fig. 5, by operation of lever 37, when the coil may beslid across the table and its surrounding platiorm for delivery, whenthe machine is ready for another operation upon again erecting fingers2.

In either raising or lowering the fingers 2 recede towards the center,due to the toggle action of links '7 on their pivotal bearings 9, beingcorrespondingly extended radially at their upper or lower positions.

As shown in Fig. 1, two of the coiling machines are arranged side byside and may be used alternately, thereby affording continuous capacityfor the strip as delivered from the mill. The machine as a whole is verycompact, simple, and strong, and well adapted to its intended use. Itovercomes the objection of lifting or prying off the coil from avertically immovable core, greatly reduces the time of the completeoperation, and also overcomes the objection of all obstructing mechanismabove the table.

It may be changed or varied in construction or difierent details by theskilled mechanic, but all such changes are to be understood as withinthe scope of the following claims.

What I claim is:

1. A coiling machine having a vertically movable laterally adjustableseries of fingers forming a grasping, winding and .releasing core, andmeans efiecting inward lateral movement of the fingers simultaneous withtheir downward vertical movement.

2. A coiling machine having a vertically movable laterally adjustableseries of fingers forming a grasping, winding and releasing core, andmeans for actuating them embodying controlling links for effectinginward lateral movement of the fingers simultaneous with their downwardvertical movement.

3. A coiling machine having a vertically stationary rotatable" table anda grasping, winding and releasing core consisting of an annular seriesof vertically movable laterally adjustable fingers extendingtherethrough and means effecting inward lateral movement of the fingerswhile maintainin their erect position and while effecting s1- multaneousdownward movement thereof.

4. in a coiling machine, a supporting standard, a rotatable spindletherein having an upper table, a series of vertically and inwardlymovable fingers forming a circular winding core extending upwardlythrough the center of the table, means for lowering the fingerssimultaneously with their inward movement, and for raising them.
